SlNGLETREE-IRON.

SPECIFICATION forming part of Letters Patent No. 394,445, dated December 11, 1888.

Application filed June 13, 1888. Serial No. 276,903. (No model.)

To all whom, it may concern:

Be it known that 1, JOHN LUTHER BLAKE, a citizen of the United States, and a resident of Mobile, in the county of Mobile and State of Alabama, have invented certain new and useful Improvements in Singletree-Irons; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my improved singletree-iron, showing the same secured in operative position to the end of a singletree, and Fig. 2 is a transverse vertical sectional view of the same.

Similar letters of reference denote corresponding parts in both the figures.

My invention has relation to irons for singletrees; and it consists in the novel manner of removably securing the same to the said singletree, as will be hereinafter more fully r set forth.

In the accompanyingdrawings, the letter A denotes the singletrec of the usual construction, and B indicates the iron formed with the eye 0 and with a transverse screw-threaded perforation, D. This iron is slipped upon the end of the singletree, which is of less circumference than the iron, and a locking-plate, E, inserted in the space between the iron and the singletree. This plate is forced against the singletree by means of a set-screw, F, screwed through the transverse aperture D, thus securely holding the iron in place. A seat is preferably formed in the lockingplate, as shown at F, for the inner end of the set-screw. \Vhen the ends of the singletrees are rounded, as shown in the drawings, the iron is also rounded and the locking-plate slightly curved,

so as to conform with the singletree; but should the singletree be formed square the locking-plate and the iron will be constructed accordingly.

The object and advantages of my invention will readily suggest themselves without requiring an extended description.

It will be seen that the iron can easily and quickly be removed afterhaving become worn and replaced with a new one, while the device is simple in construction, inexpensive to manufacture, and is exceedingly useful for the purpose for which it is designed.

Having thus described my invention,I claim and desire to secure by Letters Patent of the United States 1. The combination of a siugletree-iron of the usual construction and formed with a transverse screw-threaded aperture, with a set-screw passing through said aperture, and a locking-plate.

2. The combination, with a singletree-irou of the usual construction and formed with a transverse screw-threaded aperture, of a setscrew passing through said aperture, and a curved lockingplate.

3. The combination, with a singletree-iron of the usual construction and formed with a transverse screw-threaded aperture, of a setscrew passing through said aperture, and a curved locking-plate formed with a seat or depression for the inner end of the screw.

In testimony that I claim the foregoing as my own I have hereunto affixed mysignature in presence of two witnesses JOHN LUTHER BLAK E.
